[Answered] Blu-ray disc with external subtitles on PS3 help?

Hello everybody!!... i received the extended blu-ray trilogy of Lord of the Rings as a gift, but it doesn't have spanish subtitles. I really need to know how to play it with external subtitles. i have tried on showtime without positive results. I don't have blu-ray drive on my laptop so i can't save on hdd for recoding.
